A 19-year-old male has been released on police bail after reportedly scaring people at a west London university campus dressed as a clown.

The incident took place between 19.30 BST on Saturday and 01.30 on Sunday at Brunel University in Uxbridge.

The man was held by police on Tuesday afternoon on suspicion of a public order offence, but has since been bailed.

It came on the same day that a Brunel student apologised for a “chainsaw-wielding clown” prank filmed on the university’s grounds.

‘Kenny’, a self-described YouTube prankster, told BBC Radio London he was “only chasing his friends” in a video recorded on the campus.

Metropolitan Police has received several reports of “killer clowns” frightening people across the capital since last week, and are currently assessing three incidents for potential criminal offences.

"We are currently assessing a small number of reported 'killer clown' incidents in London, three of which meet the threshold of a criminal offence,” said Commander Julian Bennett.

"Our primary responsibility is identifying and investigating those incidents where a criminal offence has occurred.

"However, anti-social behaviour can leave people feeling scared, anxious and intimidated and I would urge those who are causing fear and alarm to carefully consider the impact their actions have on others."
